Robust, intelligent software for sewer network control. Minimize overflows, work smarter and protect the wastewater treatment plant with real-time dynamic control.
This animation shows how this Grundfos innovation works. How dynamic sewer control reduces overflows.
The Problem: Combined Sewer Overflows
Many cities utilize combined sewer systems, which collect rainwater runoff, domestic sewage and industrial wastewater in one pipe. Normally, the sewer system can transport it all to a treatment plant. During heavy rainfall, the amount of runoff exceeds what the system can handle. The untreated overflow runs into nearby bodies of water – rivers, lakes or even city streets.
These events, known as Combined Sewer Overflows (CSOs), are a serious concern for public health, environmental protection and regulatory compliance.
To reduce overflows, utilities are often expected to build large and expensive infrastructure such as tunnels and storage tanks — projects that can take years and cost millions of dollars/euros.
What if we could do it smarter? What if we could reduce CSOs without large infrastructural investments? This is the vision with our Grundfos innovation.
This solution offers a dynamic, data-driven approach to optimize existing assets (pumps, valves, storage) so networks make better use of the capacity they already have.
Tested in lab - Proven in Europe
Dynamic sewer control
The dynamic sewer control solution has been tested in the Grundfos Innovation Lab and implemented in several European municipalities, demonstrating its practical effectiveness in real-world applications.
Implementation of this Grundfos solution has significantly reduced sewage overflows, improved public health and environmental conditions.
Dynamic sewer control minimising overflows In Rheinfelden, Switzerland
The Swiss village of Rheinfelden has been using Dynamic Sewer Control to automatically optimise its rainwater storage tanks during thunderstorms. Thereby, it has minimised combined sewer overflows, which has been better for the community and better for the environment.
Grundfos’ innovative dynamic sewer control solution is tested in our lab
To verify the effectiveness of our dynamic control solution, we have rigorously tested it in laboratory conditions using a scaled-down wastewater network.
The tests confirm that dynamic, real-time control through Grundfos Sewer Control can significantly reduce overflows and enhance operational robustness.
The technology test results are documented in our whitepaper: “Grundfos Innovation - Lab test of a dynamic sewer control solution.”
We know every customer is unique, and so are their needs.
That is why this dynamic sewer control solution is configurable, designed to adapt to your specific requirements.
If your wastewater network includes storage, there is a good chance that this dynamic sewer control solution can utilize it more efficiently. Here are the two main principles behind the solution:
Optimizes capacity
This dynamic sewer control solution evenly distributes the system’s storage through real-time system monitoring, flow forecasts and autonomous adjustments for assets like pumps, valves and storage tanks. It dynamically optimizes capacity use by retaining water where there is unused space, thereby freeing up capacity where it is needed more. This approach maximizes storage capacity.
Utilizes the entire system
This Grundfos innovation utilizes the system by considering all storage components – CSO tanks, basins, pipes or any other parts of the infrastructure that can hold water. The optimization potential is directly related to the total storage capacity available within the system.
Grundfos is introducing a field-tested European technology to the U.S. wastewater sector. This invite-only program offers a low-risk, high-support opportunity to evaluate a dynamic control system that unlocks hidden capacity in your existing network.
